BUISSONI EBE, VIA PEBRIERS-SUR-ANDELLE, FRANCE PERFUME SPRAYEB Application filed March 16, 1928, Serial No. 95,118, and in France March 28, 1925,

This invention relates to an apparatus permitting the dissemination of perfumes in the dry state.

As is well known, in order to disseminate perfume particles, a volatile liquid carrier,

such as alcohol, in which the perfume is diluted and adapted to be atomized, is generally used, liquid carrier, on vaporizing, leaving the particles of perfume floating in the air. According to this invention, instead of a liquid carrier, I use a gas as a carrier for the perfumes and for ensuring a homogeneous dissemination in the air, the gas being compressed or even, preferably, liquefied, which permits one to obtain, under a very small volume, a very large supply of perfumed gas, and therefore has the advantage of easy transport and handling. For instance, liquid carbonic acid may be used, owing to the facility with which it can be liquefied.

Containers or cartridges, of the kind in current use, may be used as reservoirs for the compressed or liquefied gas, but my invention comprises a container adapted to the uniform dissemination of the perfumed gas in the air, as described hereafter.

Referring to the accompanying drawing, the figure represents in section, as an example, one particular design of apparatus for disseminating the perfume, according to this invention.

The apparatus for disseminating the perfume comprises a metallic cartridge a of any suitable shape or type which contains the compressed or liquefied perfumed gas; closed by a closure disc 6. The neck a of this cartridge is threaded and on it is screwed the tndy 0 of a perforator provided at the centre with a hollow needle d intended to perforate the closure disc b and having on its external face a seat 7:, which may conveniently be conical for instance, and in the face of which opens a small passage 6 passing through the body 0 and communicating with the central passage 7 of the needle 11. Packing washers g, suitably kept in position under the body 0, ensure a tight joint between this body and the upper edge of the neck of the cartrid e.

The ody 0 is threaded externally to receive a cap internally provided with a seat, adapted to come in juxtaposition with the seat 70 of the body 0, when the cap is screwed home, a packing disc 2' having for its function to ensure the tightness of the closure, 5 beinginterposed between the two seat faces. The cap 71. is perforated, preferably at the centre, with a small and very fine passage by which the issue of the perfumed gas can take place.

As shown in the illustration, the passage 0 in the body 0 and the passage y in the cap are not in line with one another, this permitting one to break effectively the disseminating jet of gas.

The filling of the cartridges can be done by placing a certain quantity of perfume in the cartridges before introducing the gas, or by causing the gas to pass before its compression and until more or less complete saturation in chambers or tanks suitably provided withbaflles and containing the perfume in the liquid or the dry state, pulverulent or otherwise; the gas is then compressed u to liquefaction and introduced in the cartri ges.

In the example illustrated in the drawing the closure disc 6 of the cartridge is perforated by the needle (1, but, as the cap is screwed home, no gas issues by the passage 7' of this cap. If the latter is unscrewed, the communication between the passage j of the stopper and the passages e and f of the body 0 and of the needle will be established, so that the perfumed gas will be projected by the central orifice of the stopper. The force of projection will be regulated by unscrewing more or less the cap it. As soon as the perfumed jet is no more required, it will be sufiicient to screw back the stopper to ensure the closure and tightness of the apparatus.

When a cartridge is exhausted, it can very easily be replaced by another new cartridge containing the same or a different perfume.

The apparatus constructed in accordance with the invention presents the advantage of permitting the dissemination of perfume in the dry state; it obviates therefore the use of liquids such as alcohol, which may either stain the clothes or corrode the skin or the mucous membranes. Moreover, owing to the high compression of the gas used as carrier for the perfume, the apparatus will have in spite of its very small bulk, a considerable 5 output, equivalent to that which several litres of perfumed solution could give. Finally, it is instantaneously and very easily refilled by replacement of the cartridge.

It will he understood that the manner of construction of the apparatus described above has only been given as an example and that the details of its realization could vary within wide limits without departing from the .scope of the invention. Having thus described my invention, I

declare that what I claim and desire to secure by Letters Patent of the United States A spraying device comprising a compressed gas container closed by an air-tight sealing medium, a cap adjustably secured on the container above the sealing medium, a hollow perforating needle carried by the cap and operable thereby to perforate the sealing medium, a valve seat on the cap, a duct in said cap extending from'said valve seat to the hollow needle, and a secondary cap element adjustable on said cap and adapted to seat against the valve seat thereon to close the duct therein, and said secondary cap element having a passage therethrough not in alignment with the duct in the cap.

In witness whereof, I have hereunto signedmy name.
